TECHNICAL FIELD

The present invention relates to a device for adjusting a display, whichsupports a display such as CRT for personal computer or a televisionset, a liquid crystal display, a plasma display or a display utilizingLED in a manner so as to freely adjust the angle of the display.

BACKGROUND ARTS

In recent years, a display for displaying an image such as for apersonal computer system or a television set has been intended to belight weight. Such a type of the display is mounted in front of a framebase possessed by a device for supporting a display in such a manner asto freely adjust the angle, whereby the direction of the display can bechanged to meet the favorite of a user.

As an example of the device for supporting a display, an elevatingdevice for ascending or descending a liquid crystal monitor as disclosedin Japanese Utility Model No. 3063920. As shown in FIG. 11, theelevating device for ascending or descending a liquid crystal monitorpossesses a first supporting mechanism 201A which rotatably supports aliquid crystal 300 around a center axis O at the angel of 90° in therotating direction X2, and a second supporting mechanism 201B whichrotatably supports a liquid crystal 300 around a traverse axis O1 invertically tilting direction X3 in front of a frame base 200.

However, the elevating device for ascending or descending a liquidcrystal monitor disclosed in Japanese Model disclosed above cannotrotate and adjust the monitor in horizontal tilting direction at therotation around the vertical axis (not shown), unless the frame base 300itself rotates in the horizontal direction.

In addition, since the first supporting mechanism 201A and the secondsupporting mechanism 201B are separately assembled, the number of partsmaking up them is increased according to the increasing of the directionto be adjusted, making it difficult to suppress the increasing of thenumber of the parts.

Also, the first supporting mechanism 201A is provided at one side of aholing arm 202, which makes up the second supporting mechanism 201B, andthe other side of the holding arm 202 is rotatably supported on an upperportion of the frame base 200. Moreover, since the traverse axis O1,which becomes the center P of rotating the liquid crystal monitor 300 inthe vertically tilting direction X3, resides at a backward portion ofthe liquid crystal monitor 300 far from the liquid crystal monitor, evenif the user is intended to rotate the liquid crystal monitor 300 to aslight angle, the actual movement distance towards vertically tiltingdirection X3 becomes unduly large. Consequently, the adjustment of theframe base 200 in the height direction is required every the adjustmentof the liquid crystal monitor 300 in the vertically tilting directionX3.

Moreover, depending up the direction of the liquid crystal monitor 300,the center G of the gravity and the traverse axis O1 are sometimestilted with each other. For this reason, the force of the user foradjusting the direction of the liquid crystal monitor is not alwaysconstant. Also, if the liquid crystal monitor 300 is somewhat heavy, theliquid crystal monitor 300 can be fitted in a stable manner only withdifficulty unless an additional part such as a spring is provided.

Furthermore, when vibration occurs, the position of moving the liquidcrystal monitor 300 is sometimes changed with ease.

An object of the present invention is, therefore, to make a constructionwhich is a simple construction having a reduced number of parts andwhich makes it easy to adjust the movement of the display in the 90°revolution direction, a vertically tilting direction and horizontaldirection at a substantial constant position. Particularly, the objectof the present invention is to minimize the movement distance at thetime when the display is moved in a vertically tilting direction.Furthermore, the object of the present invention is to make the user toadjust the display always at a constant operation force and not to bringabout displacement when vibration or such occurs.

Moreover, the floor panel of the frame M can berotated in the horizontal direction, and the horizontal rotation of thefloor panel makes it possible to circulate the frame M in the verticaldirection.

Subsequently, the base member 2 has a base body 21 and a spacer 22, bothmade of a resin. At the center of the front side of the base body 21, aninserting projection 23 having a substantial rectangular shape viewingfrom the front side is formed, and a base stand 24 having a circularshape viewing from the front side is provide around the insertingprojection 23. The inserting projection 23 of the base body 21 and thefront face of the base stand 24 have the same spherical curve, so thatthe rear face of the spacer 22 is supported by these insertingprojection 23 and the front face of the base stand 24.

Furthermore, between the inserting projection 23 and the base stand 24,ribs R and R for imparting strength are provided as shown in FIG. 3. Ona rear portion of the base body 21, four bolt mounters 25, 25 . . .having bolt pores formed thereon are provided. The bolt mounters 25, 25are provided on corresponding portions of mounting stands 7A, 7A, . . .provided on an upper portion of the elevating member 7, respectively.

An inserting hole 26 as shown in FIG. 3 is formed at a center of thebase body 21. The inserting hole 26 has a circular shape viewing fromthe front side, and a nut 30 is provided on a rear portion thereof via awasher W.

The spacer 22 described above has a pedestal 27 and a rear sideinserting portion 28. The front face of the pedestal 27 of the spacer 22has a spherical shape and the center thereof is formed so that thereceiving surface 27 can be largely opened. On the other hand, the rearside inserting portion 28 of the spacer 22 has a substantial rectangularshape viewing from the front side and has a figure similar to theinserting projection 23 of the base body 21 smaller than the later asthe thickness of the inserting projection 23. The rear side insertingportion 28 of the spacer 22 is inserted into the inserting projection 23of the base body 21 to fit the spacer 22 to the base body 21.

The cap supporting member 3 has a cap body 31 and a rear side insertingportion 32. The cap body 31 makes up a part of a spherical shape havingthe substantially same curvature as that of the receiving face 27A ofthe pedestal 27 of the spacer 22, and has vertically arranged two wallportions 33A and 33B for a stopper making up a part of the stopper 6 andsix reinforcing ribs 34, 34, . . . provided in front thereof. Each ofthese wall portions 33A and 33B for a stopper is arranged so as toextend in the vertical direction and is provided so as to projecttowards the front of the member 5 for regulating an angle. On the otherhand, the reinforcing ribs 34, 34, . . . are provided so as to slightlyproject from the front surface of the cap body 31. Furthermore, at asubstantially center of the cap body 31, a spring receiver 35 is formed.The spring receiver 35 is formed in the state that it is surrounded byprojections 36 each having a circular shape viewing from the front side,and the projection 36 is provided so as to slightly project from thereinforcing rib 34 respect to the front surface of the cap body 31.

The rear side projecting portion 32 provided on a rear surface of thecap body 31 has a cylindrical shape having an external diametersubstantially the same as an inner surface of the inserting hole 26formed at the center of the base body 21, and has a through hole 38 forbolt through which a bolt 8 is bored formed at a central portionthereof. The rear side projecting portion 32 is inserted into an openingformed on the center of the pedestal 27 of the spacer 22, and isinserted into the inserting hole 26 formed at the center of the basebody 21.

The flange 4 has a panel portion 41 and a spherical portion 42 at thecenter of the panel portion 41 having a concave formed on a rear side.The panel portion 41 of the flange 4 has a rectangular shape viewingfrom the front side, and through holes 43, 43, . . . are formed of thefour corners thereof. The spherical portion 42 of the flange 4 makes upa part of the spherical surface having the substantially same curvatureas that of the receiving face 27A and the cap body 31 of the capsupporting member 3. At a central portion of the spherical portion 42,an opening 44 is largely formed into which the rear side projectingportion 32 of the cap supporting member 3 is inserted. Furthermore, thespherical portion 42 of the flange 4 is sandwiched between the receivingface 27A of the pedestal 27 of the spacer 22 and the cap body 31 of thecap supporting member 3 in a slidable manner. By such a construction,the flange 4 is held and fitted in the state that it can be rotatedaround a center axis O at the angel of 90° in the rotating direction X2,around a traverse axis O1 in vertically tilting direction X3, and arounda vertical axis O2 in horizontal tilting direction X4 (see FIG. 4).

In this case, as shown in FIG. 6, the center axis O, the traverse axisO1 and the vertical axis O2 are defined as ideal axes passing through anorigin, assuming the center P of the rotation of the flange 4 as theorigin, which will be utilized in the following description.

In front of the flange 4, the member 5 for regulating an angle isprovided. The member 5 for regulating an angle has a plate-from mainbody 51 having substantially the same sides as those of the panel 41 ofthe flange 4. Through holes 52, 52, . . . are formed on the positionscorresponding to the through holes 43, 43, . . . formed on the fourcorners of the panel portion 41 of flange 4. Furthermore, Bolts B, B, .. . are inserted into the through holes 43, 43, . . . formed on theflange 4 and the through holes 52, 52, . . . formed on the member 5 forregulating an angle, and these bolts B, B, . . . are screwed into boltpores (not shown) formed on rear surfaces of the display D shown in FIG.4. By such a construction, flange 4 and the member 5 for regulating anangle are fixed onto the display D in a co-screwing state.

In addition, four projections 53A, 53B, 53C, and 53D for a stopper,which make up a part of the stopper 6 and which project backward, areformed on the rear surface of the member 5 for regulating an angle.These projections for a stopper 53A to 53D are formed so as to have thesame projection amount, and as shown in FIG. 3, each of their lengthsare set so as to reach the wall portions 33A and 33B for a stopperformed on a front surface of the cap supporting member 3 and not toreach the reinforcing rib 34. These projections for a stopper 53A to 53Dare brought into contact with the wall portions 33A and 33B for astopper, respectively, whereby the rotation of the member 5 forregulating an angle and the display D held by the member 5 forregulating an angle as shown in FIG. 4 and FIG. 5. This makes itimpossible to revolute them any more. The stopper 6 is composed of wallportions 33A and 33B for a stopper provided on the cap supporting member3 and these projections 53A to 53D for a stopper provided on the member5 for regulating an angle make up the stopper 6, which regulates therotation range.

As shown in FIG. 3, the bolt 8 is screwed into the nut 30 provided on arear side of the base body 21. The bolt 8 has a head portion 8A having alarge diameter and a screw portion 8B formed on the edge portion. Thescrew portion 8B is screwed into the nut 30. The rear surface of thehead portion 8A is in a plate form, and a coil spring 9 is intervenedbetween the rear surface and the spring receiver 35 of the capsupporting member 3. The coil spring 9 is fitted in a slightlycontracted state.

Here, since the bolt 6 is screwed into the nut 30, the coil spring 9 isin the fixed state fixed to the base member 2. For this reason, the coilspring 9 will expand due to the reverse force to the head portion 8A. Atthis time, by the resilient force of the coil spring 9, the cap body 31of the cap supporting member 3 is applied to the resilient force in thedirection of the spacer 22. By the application of the resilient force tothe cap body 31 in the direction of the spacer 22, the spherical portion42 of the flange 4 positioned between the cap body 31 and the spacer 22is sandwiched.

As described above, the flange 4 is held by the cap supporting member 3in a manner that the flange 4 can be slid in any of the directionscenter axis O at the angel of 90° in the rotating direction X2, thetraverse axis O1 in vertically tilting direction X3, and vertical axisO2 in horizontal tilting direction X4 as shown in FIG. 2 and FIG. 3.

The device H for adjusting a display having construction as describedabove according to the present invention will now be described.

In the device H for adjusting a display, the flange 4 is sandwichedbetween the receiving face 27A of the spacer 22 and the rear surface ofthe cap supporting member 3, and the display D is held by the flange 4via the member 5 for regulating an angle. The flange 4 can be slid alongthe receiving face 27A. By such a structure, as for the display D fittedto the flange 4, the revolution around the center axis O at the angel of90° in the rotating direction X2, that around the traverse axis O1 invertically tilting direction X3, and that around the vertical axis O2 inhorizontal tilting direction X4 can be performed by only one displaymounter 1.

Subsequently, the revolution of the display D around the center axis Oat the angel of 90° in the rotating direction X2 will now be described.As shown in an ideal line (double dot line) in FIG. 5, any one of theprojections 53B and 53D for a stopper of the member 5 for regulating anangle is brought into contact with any of the wall portions 33A and 33Bfor a stopper to regulate the movement thereof. It is assumed that atthis time, the display D has been turned sideways. In order to turn thedisplay D into the lengthwise direction from this state, when thedisplay D is rotated clockwise around the center axis O shown in FIG. 2to FIG. 4, the member 5 for regulating an angle is also turned aroundthe center axis O at the angel of 90° in the clockwise rotatingdirection X2 as shown in FIG. 5. When the display D is rotated clockwiseat 90°, now any one of the projections 53A and 53C for a stopper of themember 5 for regulating an angle is brought into contact with any of thewall portions 33A and 33B for a stopper to regulate the movementthereof. At this time, the flange 4 is rotated together with the member5 for regulating an angle, and the movement is regulated just at thetime when they are rotated at 90°. This makes it possible to turn thedisplay which is in the sideway into the lengthwise way.

Next, the revolution of the display D around the traverse axis O1 invertically tilting direction X3 will now be described. As shown in FIG.6, the flange 4 can be rotated around the traverse axis O1 shown in FIG.2 to FIG. 4 relative to the base member 2 and the cap supporting member3, but the rotation range thereof is regulated. Specifically, by therotation of the display D around the traverse direction O1, when theflange 4 and the member 5 for regulating an angle is rotated around thetraverse direction O1 counterclockwise shown in FIG. 5 from the statewhere they are positioned at the center shown in the real line to betilt them downwardly, a lower rear surface of the body 51 of the member5 for regulating an angle is brought into contact with the wall 33B fora stopper. Also, when the flange 4 and the member 5 for regulating anangle is rotated around the traverse direction O1 clockwise shown inFIG. 5 to be tilt them upwardly, an upper rear surface of the body 51 ofthe member 5 for regulating an angle is brought into contact with thewall 33B for a stopper. This makes it possible to turn the direction ofthe display D in vertically tilting direction X3.

Here, when the body portion 51 of the member 5 for regulating an angleis directed downwardly, the projection 53D for a stopper residing abovethe body portion 51 is never come into contact with the wall 33A for astopper. However, when the projection 53D for a stopper residing abovethe member 5 for regulating an angle is not brought into contact withthe wall 33A for a stopper, the projection 53B for a stopper residingbelow the member 5 for regulating an angle is come into contact with thewall 33B for a stopper residing below the cap supporting member 3. Inthis state, there is a fear that the projection 53B for a stopperresiding below the member 5 for regulating an angle is bumped againstthe reinforcing rib 34 of the cap supporting member 3. However, as shownin FIG. 6 as a broken line, the length of the projection of thereinforcing rib 34 is set to be short, i.e., set so that even if theprojection 53B for a stopper comes the closest to the reinforcing rib 34does not bump against the projection 53B for a stopper. Similarly, it isset that other projections 53A, 53C, and 53D come the closest to thefront surface of the cap body 31, they do not bump against the frontsurface of the cap body 31.

As described above, the body portion 51 of the member 5 for regulatingan angle is directed downwardly, the rotation range in an upperdirection of the member 5 for regulating an angle and that of the flange4 can be regulated by means of the projection 53B for a stopper residingbelow the member 5 for regulating an angle and the wall 33B for astopper. Conversely, when the body portion 51 of the member 5 forregulating an angle is directed upwardly, the projection 53B for astopper residing below the member 5 for regulating an angle is not comeinto contact with the wall 33B for a stopper, but the projection 53D fora stopper residing above the member 5 for regulating an angle is comeinto contact with wall 33A for a stopper residing above the capsupporting member 3. As described above, when the body portion 51 of themember 5 for regulating an angle is directed upwardly, the rotationrange in a lower direction of the member 5 for regulating an angle andthat of the flange can be regulated by means of the projection 53D for astopper residing above the member 5 for regulating an angle and the wall33A for a stopper of the cap supporting member 3.

At this state, for example, the display D is assumed to be a lengthwisedirection, if the display D resides in a width direction, as shown inFIG. 5 as a real line, the projection 53A for a stopper is placed on anupper portion and the projection 53C for a stopper is placed on a lowerportion. By functions similar to those of the projections 53D and 53 fora stopper, the rotation of the display D can be regulated. What is more,by placing the stopper at the position where the display D is rotatedjust at 90°, the display D can easily be set in both the lengthwisedirection and the width direction.

In the rotation of the display D shown in FIG. 4 around the verticalaxis O2 in horizontal tilting direction X4, in the case where no stopperis provided, the rotation is similar to the rotation of the display Daround the traverse axis O1 in vertically tilting direction X3. However,in the case where the projections for a stopper is provided, therotation of the display D around the vertical axis O2 in horizontaltilting direction X4 is regulated.

Consequently, in the device H for adjusting a direction of a displayaccording to the present invention, the rotation of the display around acenter axis O at the angel of 90° in the rotating direction X2, thataround a traverse axis O1 in vertically tilting direction X3 and thataround a vertical axis O2 in horizontal tilting direction X4, can beperformed only by sandwiching the flange 4 by the base member 2 and thecap supporting member 3 in the display mounter 1. Consequently, unlikethe prior art in which supporting mechanisms are separately provided inorder to meet all the rotation of the display D, a number of parts canbe decreased.

Also, in the device H for adjusting the direction of a display accordingto the present invention, the center P of the rotation of the flange 4(see FIG. 10), which slides along the receiving face 27A of the pedestal27 of the spacer 22, in the vertically tilting direction X3 ispositioned in front of the receiving face 27A. For this reason, theflange 4, the member 5 for regulating an angle and the display D arerotated around a point positioned in front of the receiving face 27A asa center. By such a construction, when the display is rotated around thevertically tilting direction X3, the movement distance can be reduced incomparison with the prior art.

Furthermore, since the center P of the rotating the flange 4 ispositioned in front of the receiving face 27A, the center P of therotation can be substantially accorded with the center of the gravity ofthe display D. Specifically, In this embodiment, the center P of therotating the display D in the vertically tilting direction X3 isaccorded with the center of the gravity of the display D.

As described above, since the center P of the rotating the display D inthe vertically tilting direction X3 is accorded with the center of thegravity of the display D, the center of the gravity of the display D canbe substantially unchanged even when the display is rotated.Consequently, the user can rotate the display D always by substantiallythe same force, and the display D can effectively be prevented frombeing felt down towards the front side.

Preferred embodiments of the present invention have been described, butthe present invention is not restricted thereto. For example, in orderto prevent the display from being rotated due to vibration or such whenthe display is in the lengthwise or width direction, a ball click forimparting so called click feeling may be provided on the flange and thebase member.

Also, the parts described above may be produced in a unified state tofurther decrease the number of parts. It is noted that materials foreach parts may be freely selected, for example, part of or all of theparts may be made of, e.g., a metal, a resin, a reinforcing plastic, orsuch.

Subsequently, a second embodiment of the present invention will bedescribed in detail by referring to the drawings. FIG. 7 is an explodedperspective view showing the device for adjusting a direction of adisplay according to the second embodiment partially showing the mainportions, FIG. 8 is a front view thereof, FIG. 9 is a plane viewthereof, and FIG. 10 is a perspective view thereof.

As shown in FIG. 7, a device H′ for adjusting a direction of a displayaccording to the present invention has a base member 101, spiral springs102 and 102 and an elevating member 103. Spacers 104 and 104 are fittedto both ends of the elevating member 103, a center guide member 105,which fixes the height position of the elevating member 103 relative tothe base member 101 is provided at the central position of elevatingmember 103 in the height direction. To a display mounter 106 is similarto that of the first embodiment.

The base member 101 has a pedestal 111 and a holder 112. a circularrotation table 113 shown in FIG. 9 as a broken line is provided withinthe pedestal 111 so as to be able to rotate in the vertical direction.The holder 112 is ma de of a metal, stands along one end of the pedestal111, and guide portions 114 and 115, which form slide groove extendingtowards a vertical direction, are proved on both ends of the holder 112viewing from the front side. The space between the guide portions 114and 115 is opened at the front side, and has a center guide portion 116for connecting the guide portions 114 and 115 provided at a rear side.The center guide portion 116 of the holder 112 is formed so that it isbent to slightly project toward a front side, and has a through hole 117formed on an upper side thereof. As described above, since the centerguide portion 116 of the holder 112 is formed into a shape so as toproject towards a front side, and since it is guided and supported bythe center guide member 105, it prevents the device H′ for adjusting adirection of a display from being felt down towards the front side dueto the weight of the display D and from being unduly moved towards ahorizontal direction.

Spiral springs 102 and 102 are provided within the guide portions 114and 115, respectively, and one ends of the spiral springs 102 and 102are fixed onto inner sides of the guide portions 114 and 115 by means offixing members 121 and 121. The spiral springs 102 and 102 are fitted sothat the winding portions thereof are wounded following the descendingof the elevating member 103. Also, when the winding portions of thespiral springs 102 and 102 are wounded as described above, the resilientforces thereof are directed towards a direction that the elevatingmember 103 is pushed up. In this case, the resilient forces of thespiral springs 102 and 102 are always at substantial constant regardlessof an amount of winding.

The elevating member 103 is made of a metal, and has inserting portions131 and 132 which are inserted into the guide portions 114 and 115 ofthe base member 101, respectively provided thereon. These insertingportions 131 and 132 of the elevating member 103 are inserted into theguide portions 114 and 115 of the base member 101 so that the elevatingmember 103 may be relatively moved toward the vertical direction (Zdirection in FIG. 8) relative to the base member 101.
